CONSPIRACY: Theresa Allore
When Theresa Allore vanishes from her college campus in Quebec, Canada, in 1978, local police dismiss her as runaway and force her family to start their own investigation that would span across 45 years. Over the decades, they piece together evidence and uncover an array of conspiracies from a potential serial killer on the prowl to the possibility of corrupt law enforcement.
